Method description

Cardiomyocytes derived from induced pluripotent stem cells (iPSC-CMs) offer an attractive platform for cardiovascular research, including disease modeling, drug toxicity testing and development of regenerative therapies. Patient-specific iPSC-CMs are very useful to study disease pathogenesis and have a huge potential for evaluation of disease prognosis and development of personalized treatment. In our research group we study inherited cardiac arrhythmias (currently with a focus on Brugada syndrome) and cardiomyopathies. We create iPSC-CM models, either patient-derived or using CRISPR/Cas, to evaluate the functional effect of specific genetic variants, assist the search for modifier genes and novel therapeutic targets, and screen for novel drug compounds.

Pros, cons & Future potential


Human model mimicking the native cardiomyocyte environment, patient-based disease model recapitulating full genomic background.


Relative immaturity of the cells, variability of the phenotype of the final iPSC-CM model


Improved protocols for more standardized differentiation and maturation of the cardiomyocytes.

Future & Other applications

iPSC-CMs can as well be used for drug cardiotoxicity screening and regenerative therapies after further improvements and validation.
